Yoshida, an employee at a large IT company, falls in love with his colleague, Airi Goto. After five years, he finally dares to invite her on a date: a fun trip to the zoo, dinner in an expensive restaurant… The day that seemed promising turned into a night of a broken heart. Drunk, saddened, and rejected, Yoshida on his way home met a lonely high school student, Sayo Ogihara. Without beating around the bush, she offered “that” in exchange for a place to stay, but Yoshida, nobly refusing the offer, let her spend the night for free.
The next morning Sayo told Yoshida how she ended up in Tokyo: she ran away from her parents in Hokkaido, and over her half-year trip she often offered her “services” in exchange for a roof over her head. Seeing the desperation and pain in the girl’s eyes, Yoshida allows her to stay for a while. From that day on, a new chapter opens in Sayo’s and Yoshida’s lives.
